The HDB8228 HDEC Midsize Format Backplane

HDEC Series midsize format backplane supports one dual-processor HDEC Series SHB and up eight PCI Express option cards. All card slots are designed for the Gen3 PCIe electrical interface and are equipped with x16 PCIe mechanical connectors. Four of the card slots are driven with Gen3 PCI Express x16 electrical interfaces and the remaining four slots support a x4 PCIe electrical interface.

Key features of the HDB8228 Midsize Format Backplane include:

  • Eight total PCIe 3.0 option card slots available:
    • 4-x16 PCIe gen 3 and 4-x4 PCIe gen 3 (x16 mechanical)
  • Numerous device I/O connections within each backplane segment simplifies system integration, and cable routing
    • 6 – SATA/600 system headers
    • 2 – USB3 interface header connections
    • 4 – Rear Chassis USB2 interface ports
    • 1 – Serial port header
    • 4 – System fan headers with built-in fan speed monitoring
  • Ideal midsize format backplane for supporting standard 4U rackmount computer chassis
  • Long life cycle with 7+ year backplane availability
Trenton designs all of our HDEC Series system host boards and backplanes to fully support the PCI Express auto-training function that ensures SHB-to-option card communications regardless of PCI Express interface type or link width.  This SHB and backplane design feature maximizes system flexibility by enabling system support for standard PCIe 3.0, 2.0 or 1.1 option cards having various PCIe electrical interface link widths such as x16, x8, x4 and x1.

The HDB8228 HDEC Series Midsize Format Backplane is designed and manufactured in the USA, and backed by our 5-year factory warranty.

 

Tech Specs

Model Number

HDB8228

Form Factor

HDEC Series midsize format backplane supports one dual-processor HDEC Series SHB and up eight PCI Express option cards. All card slots are designed for the Gen3 PCIe electrical interface and are equipped with x16 PCIe mechanical connectors. Four of the card slots are driven with Gen3 PCI Express x16 electrical interfaces and the remaining four slots support a x4 PCIe electrical interface.

Mechanical

Board dimensions: 12.3“/312mm x 12.9“/328mm (midsize format)
The nominal backplane thickness is 0.080”; however, the backplane mounting holes are recessed 0.018” on the bottom to provide an effective PCB thickness of 0.062” for use in the chassis design process.

Configuration

Four segment backplane with one x16 PCI Express card slot, and one HDEC Series system host board slot in each backplane segment
Each backplane segment’s PCIe slot is driven with a native PCIe 3.0 link direct from the processors on a compatible HDEC Series system host board; such as Trenton’s HEP8225, plugged into the segment’s SHB slot.
